I have had soem success with PhotoReading. I have found that to the extent that I use it, to that extent, it works.
I do think that the mindset needed for something like this does have to do with at least a playful attitude, if not a total suspension of disbelief or skepticism
This is not a technique, but rather a new and different approach to learning and reading. I would not be surprised at all to read a lot of negative reviews on Amazon or anywhere, because this kind of learning or maybe better, "re-learning", is not something you can just run through a menu or go through a list of solutions and have it "work for you". It is rather something that takes a bit of a reorientation and changing of some very, very died-in-the-wool habits and beliefs (e.g. "it is very important to read every word" Why? Where is that written?).
The PhotoReading approach or System is a far superior way of approaching reading and learning. Will it work for everyone? I would have to say, "No!" But the reason why for many people is that it is asking something of them that they are unwilling to do: become a more active playful participant in the reading and learning process.
I for one am glad I discovered it and though I have not yet "mastered" it, I look forward to continue to improve and am very grateful to having discovered it.
My two bits, for what it's worth. YMMV
